While I sympathize with the sentiment, that creating some kind of censorship dystopia will magically solve the problem, the idea has no traction when most of the people doing so make less than $1 a day somewhere in a remote corner of the world. This is the problem I have with climate activism.

The best way to reduce pollution is to raise the standard of living for people around the world. People who are wealthy can afford cleaner forms of energy, they can afford to dispose of trash cleanly, they can afford to recycle. People that are poor have nothing to lose and don't care about "environmental authorities". "Let's ban X", "Let's force people to do Y" and "Throw them in jail" is not a reasonable or effective way to solve problems. It also further divides people and does more to hurt your cause than to promote it.
